| Abstract: | The regeneration of the coked catalyst of gas-phase perchloroethylene hydrofluorination to pentafluoroethane (Freon 125) has been investigated at 370–420°C and atmospheric pressure. The parameters of the mathematical model (rate constant and activation energy) for coke combustion have been determined from the experimental data obtained in a laboratory reactor and from thermoanalytical data. The data obtained have provided a basis for optimization of catalyst regeneration in an industrial reactor. |
